"It's funny, the left says they really respect women, and then when given an opportunity to respect a woman like that, they boo and hiss," he said about audience members at the female entrepreneurship discussion in Berlin.

"So I don't really get what's going on here, but I really liked how she was speaking into that microphone," he said, looking directly into the camera.

Mr Watters has drawn controversy for segments about New York City's homeless population and the city's Chinatown district.

Last month he interviewed President Donald Trump while aboard Air Force One, becoming one of only 45 people that the president follows on Twitter.

The sudden announcement comes as the network scrambles to recover from multiple allegations of sexual harassment that have led to the resignations of Mr O'Reilly and Fox News founder and CEO Roger Ailes.

On Tuesday, long-time Fox reporter Kelly Wright joined a lawsuit with 12 other current and former employees alleging that executives knew about sexual and racial discrimination, but did nothing to stop it.

Mr Wright, who has worked at Fox since 2003 accused the network of "plantation-style management," saying that co-president Bill Shine obsessively focused on Mr Wright's race, which is African-American.

He also said that Mr O'Reilly refused to show a series on his programme about the racial divide in Ferguson, Missouri, because it showed "blacks in too positive a light".

Fox News has said it "vehemently denies the race discrimination" allegations.

US media-watchers and on-air news personalities have taken to Twitter to react to Mr Watters comment.
